Did you know?
The majority of local authorities around the UK require noise from new plant equipment to achieve no more than minus 10dB below the measured 'background noise level'.
* Please enter manufacturers noise level into these fields. This is usually referred to as an 'SPL' or Sound Pressure Level - typically expressed at 1 metre.
Combined Equipment Noise Level 'Combined' or 'Cummulative' noise is the total noise produced by 2 or more noise sources operating simultaneously. For example, 3dB is added to 2 identical noise sources.
Resultant Noise Level This is the total predicted noise level which takes into consideration, all equipment, distance and reflective acoustic corrections.
